The quandle and group for higher-dimensional and virtual knots [PDF]

arXiv, 2009
Joyce has shown that the fundamental quandle of a classical knot can be derived from consideration of the fundamental group and the peripheral structure of the knot, and also that the group and much of the peripheral structure can be recovered from the quandle.
